ABSTRACT
This paper responds the WFD 2000/60 provisions related to the rivers longitudinal connectivity and to increasing public interest regarding the sustainable development of river systems, especially for the heavy modified water bodies. The aim of this work was to propose technical solutions for ensuring fish migration upstream and downstream the CET1 Oradea weir dam, placed on the River Crişul Repede. The aim of this work is to present a solution to facilitate fish migration, by proposing technical solutions that intend creation of fish pass in order to help the migratory species present in study area, to migrate upstream and downstream the CET1 Oradea dam. All components of the proposed fish pass system (mobile basins, flexible plastic tubes, transportation systems, etc.) are designed to transport fish up- and downstream the dam, being placed on the second and third dam’s piles. Taking into account the local specific conditions and technical characteristics of the placement, the proposed system can be successfully used at other dams of this type, that offers to the proposed solution a practical value.
